Editing Cem Sultan (section)

== In Cairo ==
The Mamlūk sultan [[Qāʾit Bāy]] (r. 1468–1496) received Cem with honour in Cairo, and Cem took the opportunity to go on pilgrimage to [[Mecca]], making him the only Ottoman prince to have made the pilgrimage.<ref name=":1" />

In Cairo, Cem received a letter from his brother, offering Cem one million [[akçe]]s (the Ottoman currency) to stop competing for the throne. Cem rejected the offer, and in the following year he launched a campaign in Anatolia under the support of Kasım Bey (Qāsım Beğ), heir of the ruling house of Karaman, and the ''[[Sanjak-bey|sanjek bey]]'' of Ankara. On 27 May 1482 Cem besieged Konya but was soon defeated and forced to withdraw to [[Ankara]]. He intended to give it all up and return to Cairo but all of the roads to Egypt were under Bayezid's control. Cem then tried to renegotiate with his brother. Bayezid offered him a stipend to live quietly in Jerusalem but refused to divide the empire, prompting Cem to flee to [[Rhodes]] on 29 July 1482.
